Question

Quizplus · Accepted Answer

Hydrostatic pressure is the force that moves fluid out of capillaries, while colloid osmotic pressure (also called oncotic pressure) is the opposing force that moves fluid into capillaries. Systolic and diastolic pressures are terms used to describe blood pressure, but they are not directly related to capillary exchange. Blood and interstitial pressures also play a role in capillary exchange, but they do not directly correspond to the forces moving fluid in and out of capillaries. Plasma and extracellular pressures are not commonly used terms in describing capillary exchange.
